The ratio of men to women at the picnic is 4:5,if there are 819 people, how many men are there in the picnic​

Answers

There are 364 men at the picnic

Describe Equation?

Equations can be written in many forms, but they all have the same basic structure: an expression on the left-hand side of the equals sign, and an expression on the right-hand side of the equals sign, with the equals sign itself indicating that the two expressions are equal.

Equations can be solved using a variety of techniques, including algebraic manipulation, substitution, and graphing. The goal of solving an equation is to find the values of the variables that make the equation true. In some cases, there may be multiple solutions to an equation, or no solutions at all.

Let the number of men be 4x, and the number of women be 5x.

According to the problem, the total number of people is 819, so:

4x + 5x = 819

Simplifying and solving for x, we get:

9x = 819

x = 91

Therefore, the number of men at the picnic is:

4x = 4(91) = 364

So there are 364 men at the picnic.

Answers

After answering the presented question, we can conclude that They are equation still pleased with the quantity of pizza they received, although it is less than in the previous scenario.

What is Quotient?

A quotient refers to the result obtained when one quantity is divided by another. For example, if you have 10 apples and you want to divide them equally among 2 people, each person would get 5 apples. The quotient in this case is 5, which represents the number of apples that each person would receive.

The quotient can be expressed in different forms, depending on the situation. If you are dividing two integers, the quotient can be a whole number (also known as an integer quotient) or a fraction (also known as a rational quotient). For example, if you divide 10 by 3, the quotient is 3 with a remainder of 1, which can be expressed as [tex]3 + 1/3[/tex] or as the fraction 10/3.

In algebra, the quotient can also refer to the result obtained when dividing two algebraic expressions. For example, if you divide [tex]x^2 + 3x + 2[/tex] by [tex]x + 1,[/tex] the quotient is [tex]x + 2[/tex], which represents the quotient of the division.

The concept of quotient is also used in other areas of mathematics, such as in modular arithmetic and in group theory, where it refers to the result of dividing one element of a group or a ring by another.

Answers

Therefore, the probability that a randomly selected family owns a cat is 0.257. Therefore, the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat is 0.778.

What is probability?

Probability is a branch of mathematics that deals with the study of random events or situations. It involves the quantification of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, with 0 representing impossibility and 1 representing certainty. The theory of probability provides a framework for making predictions, analyzing data, and making decisions in situations involving uncertainty or randomness.

Here,

Let's use the following events:

D: family owns a dog

C: family owns a cat

From the problem statement, we know:

P(D) = 0.3

P(C|D) = 0.2

P(C) = 0.34

1. To find the probability that a randomly selected family owns a cat, we can use the law of total probability:

P(C) = P(C|D) * P(D) + P(C|not D) * P(not D)

We don't know P(C|not D), but we can find it using the fact that P(not D) = 1 - P(D):

P(C|not D) = (P(C) - P(C|D) * P(D)) / P(not D)

P(C|not D) = (0.34 - 0.2 * 0.3) / (1 - 0.3)

P(C|not D) = 0.2857

Substituting the values:

P(C) = 0.2 * 0.3 + 0.2857 * 0.7

P(C) = 0.257

2. To find the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat, we can use Bayes' theorem:

P(not D|C) = P(C|not D) * P(not D) / P(C)

Substituting the values:

P(not D|C) = 0.2857 * 0.7 / 0.257

P(not D|C) = 0.778

Find the vertex of the quadratic function f(x)=x^2-6x+1

Answers

Answer:

(3, 8).

Step-by-step explanation:

1. Write the expression in general form.

General form is: y = ax² + bx + c.

[tex]y=x^2-6x+1[/tex]

2. Use the following formula to find the "x" coordinate of the vertex.

Formula: [tex]x=-\frac{b}{2a}[/tex]

3. Identify "b" and "a" from the general form.

So "b" should be the coefficient of the "x" variable, that value is: -6.

Now, the "a" value is implicit, since the x² doesn't have any numbers in front of it. Therefore, the value of "a" is 1.

4. Use the values to calculate the "x" coordinate of the vertex.

[tex]x=-(\frac{(-6)}{2(1)})\\ \\x=-(\frac{-6}{2})\\ \\x=-(-3)\\ \\x=3[/tex]

5. Substitute "x" by the calculated value (3) in the original function formula to find the "y" coordinate of the vertex.

[tex]y=x^2-6x+1\\ \\y=(3)^2-6(3)+1\\ \\y=9-18+1\\ \\y=-8[/tex]

6. Write the ordered pair of the vertex.

substracts 5 - 3 1/3

Answers

Answer:

5/3

1 2/3

Step-by-step explanation:

5 - 3 1/3 can be simplified as follows:

5 - 3 1/3 = 5 - (3 + 1/3) [grouping the whole number and fraction together]

= 5 - (10/3) [converting the mixed number to an improper fraction]

= 15/3 - 10/3 [finding a common denominator for subtraction]

= 5/3

Therefore, 5 - 3 1/3 is equal to 5/3.

To subtract these, we need to convert both into improper fractions for simplification:

5 converts to 15/3 because 15 / 3 = 5, where 3 is our denominator.

3 1/3 converts to 10/3 because (3 • 3) + 1 = 10, where 3 also is our denominator.

Now we can subtract easily.

15/3 - 10/3 = 5/3

5/3 converts to 1 2/3 because 3 • 1 = 3, and 2 is leftover.

5 - 3 1/3 = 1 2/3, or 5/3.

The two points on the line to graph the function is (0, -16) and (1, -53).

What are coordinates?

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. The order of the coordinates is crucial, and they are sometimes recognised by their position in an ordered tuple and occasionally by a letter, as in "the x-coordinate". In elementary mathematics, the coordinates are assumed to be real numbers, although they might instead be complex numbers or components of a more abstract system, such a commutative ring.

The given function is:

q(x)=3x−(2+5x)8

To find two points on the line to graph the function we substitute different values of x.

For x = 0:

q(x)=3x−(2+5x)8

q(0) = 3(0) - (2 + 5(0))8

q(0) = -16

For x = 1:

q(x)=3x−(2+5x)8

q(1) = 3(1) - (2 + 5(1))8

q(1) = 3 - (7)8

q(1) = -53

Hence, the two points on the line to graph the function is (0, -16) and (1, -53).

Case 3: s = 17π / 6 ft, A = 17π / 4 ft²

Case 4: s = 11π / 2 in, A = 33π / 2 in²

Case 5: s = 116π / 9 yd, A = 928π / 9 yd²

Case 6: s = 13π / 12 ft, A = 13π / 8 ft²

How to determine the arc length and the area of a circle sector

In this problem we need to determine the arc length (s), in yards or inches, and the area (A), in square yards or square inches, of a circle sector, whose formulas are listed below:

Arc length

s = (θ / 180) · π · r

Area

A = 0.5 · (θ / 180) · π · r²

Where:

θ - Measure of the central angle, in degrees. r - Radius, in yards or inches.

Now we proceed to determine the arc length and the area for each case:

Case 1 (r = 11 yd, θ = 165°)

s = (165 / 180) · π · 11

s = 121π / 12 yd

A = 0.5 · (165 / 180) · π · 11²

A = 1331π / 24 yd²

Case 2 (r = 14 in, θ = 150°)

s = (150 / 180) · π · 14

s = 35π / 3 in

A = 0.5 · (150 / 180) · π · 14²

A = 245π / 3 in²

Case 3 (r = 3 ft, θ = 170°)

s = (170 / 180) · π · 3

s = 17π / 6 ft

A = 0.5 · (170 / 180) · π · 3²

A = 17π / 4 ft²

Case 4 (r = 6 in, θ = 165°)

s = (165 / 180) · π · 6

s = 11π / 2 in

A = 0.5 · (165 / 180) · π · 6²

A = 33π / 2 in²

Case 5 (r = 16 yd, θ = 145°)

s = (145 / 180) · π · 16

s = 116π / 9 yd

A = 0.5 · (145 / 180) · π · 16²

A = 928π / 9 yd²

Case 6 (r = 3 ft, θ = 65°)

s = (65 / 180) · π · 3

What precisely is a triangle?

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.  

So, for triangle ABC with sides AB, BC, and AC, we have:

[tex]AB + BC > AC\\16 + 25 > AC\\41 > AC\\BC + AC > AB\\25 + AC > 16\\AC > -9 \\AB + AC > BC\\16 + AC > 25\\AC > 9\\[/tex]

Work accounts for approximately 60° of the pie chart, or 15.48% of the total 360°.

How to solve

To calculate a pie chart, first, categorize the data and calculate the total.

Each slice of the pie chart represents a numerical value and has a size proportional to the value.

The sum of all the data is equal to 360°, with the total value always being 100%.

To find the percentage for each slice of the pie chart, divide the categories by the total and convert them into percentages.

Finally, calculate the degrees using the formula (Given Data/Total value of Data) × 360°.

For example, let's say we have data on sleep, work, family care, personal care, and leisure, with a total of 168 hours.

To find the percentage for each category, we can use the following calculations:

Sleep: 54/168 x 100 = 32.14%Work: 28/168 x 100 = 15.48%Family care: 18/168 x 100 = 10.71%Personal care: 20/168 x 100 = 11.90%Leisure: 48/168 x 100 = 28.57%

What is sorting?

Sorting is the process of arranging or categorizing a set of items in a particular order or sequence according to specific criteria. It is a fundamental operation in computer science and is used extensively in various applications such as data analysis, information retrieval, and database management.

In general, sorting involves comparing elements of a collection, such as an array or a list, and rearranging them according to a predetermined order. The order can be based on a variety of factors, such as numerical value, alphabetical order, or date/time stamp. The two main categories of sorting algorithms are comparison-based sorting and non-comparison based sorting.

Some common sorting algorithms include bubble sort, insertion sort, selection sort, quicksort, merge sort, and heapsort. Each algorithm has its own advantages and disadvantages, and the choice of algorithm depends on the specific application and the characteristics of the data being sorted.

Jaylon works for a concrete company
His customer would be him to pour a new driveway. The concrete must be 3/4 fr deep.

Look at the drawing and calculate the number of cubic feet of concrete he will need to bring to the job.

Answers

Answer:

volume = length × width × depth

Assuming that the driveway has a rectangular shape, you can measure the length and width of the area to be covered and multiply by the depth of 3/4 ft (which is 0.75 ft) to get the volume in cubic feet.

For example, if the driveway is 20 ft long and 10 ft wide, the volume of concrete needed would be:

volume = length × width × depth

= 20 ft × 10 ft × 0.75 ft

= 150 cubic feet

The measure of angle ZUB is 32.8°.

What precisely is a triangle?

A triangle is a closed, double-symmetrical object composed of three line segments known as sides that intersect at three points known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides.

Triangles are classified as acute (all angles are less than 90 degrees), okay (one angle is equal to 90 degrees), or orbicular (all angles are greater than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighborhood, b is the triangle's base, and h is the triangle's height.

Since the angles given are 90 degrees and 57.2 yοu can add thοse tοgether then subtract them  frοm 180 tο find the answer.

180 - 90 + 57.2 = 32.8

Thus,

Solve the differential equation with
the given initial condition.
Dy/dx=3x/√y
(0,1)

Answers

The solution to the differential equation dy/dx = 3x/√(y) with initial condition (0,1) is y = ((9/4) × x² + 1)^(2/3).

Describe differential equation?

Differential equations are used to model a wide variety of physical, biological, and economic systems, including the motion of objects under the influence of forces, the spread of disease in a population, and the behavior of financial markets.

There are many different types of differential equations, including ordinary differential equations (ODEs) and partial differential equations (PDEs). ODEs involve a single independent variable and its derivatives, while PDEs involve multiple independent variables and their derivatives.

To solve the differential equation dy/dx = 3x/√(y), we can separate the variables by multiplying both sides by √(y) and dividing both sides by 3x:

dy/dx = 3x/√(y)

√(y) dy/dx = 3x

√(y) dy = 3x dx

Integrating both sides:

∫√(y) dy = ∫3x dx

(2/3)*y^(3/2) = (3/2)*x² + C

where C is the constant of integration.

To find the value of C, we can use the initial condition (0,1), which means y=1 when x=0:

(2/3)*y^(3/2) = (3/2)*x² + C

(2/3)*1^(3/2) = (3/2)*0² + C

C = (2/3)

Substituting C = 2/3 back into the equation, we get:

(2/3)×y^(3/2) = (3/2) × x² + 2/3

y^(3/2) = (9/4) × x² + 1

y = ((9/4) × x² + 1)^(2/3)

Therefore, the solution to the differential equation dy/dx = 3x/√(y) with initial condition (0,1) is y = ((9/4) × x² + 1)^(2/3).

What referents would you use to estimate the length, in both SI units and imperial units, of the Victoria (Old Traffic) Bridge in Saskatoon? Explain how you could measure the length in both units. ​

Answers

Step-by-step explanation:

The Victoria (Old Traffic) Bridge in Saskatoon, Canada, has a length of approximately 230 meters (755 feet). To estimate the length of the bridge in both SI and imperial units, you can use the following referents:

SI Units:

To estimate the length of the bridge in SI units, you can use meters as the referent. The length of the Victoria Bridge can be measured using a distance measuring device such as a surveyor's wheel, a laser distance meter, or a tape measure. You can start at one end of the bridge and measure the distance to the other end. This will give you an accurate measurement of the length of the bridge in meters.

Imperial Units:

To estimate the length of the bridge in imperial units, you can use feet as the referent. You can use a tape measure or a distance measuring wheel that measures in feet. You can start at one end of the bridge and measure the distance to the other end. This will give you an accurate measurement of the length of the bridge in feet.

To convert the length from meters to feet or vice versa, you can use the following conversion factors:

1 meter = 3.28 feet

1 foot = 0.3048 meters

Therefore, to convert the length of the Victoria Bridge from meters to feet, you can multiply the length in meters by 3.28. For example, 230 meters x 3.28 = 754.4 feet (rounded to the nearest tenth).

To convert the length of the Victoria Bridge from feet to meters, you can multiply the length in feet by 0.3048. For example, 755 feet x 0.3048 = 230.1 meters (rounded to the nearest tenth).

If cos 55° = p determine the value of cos 5° in terms of p.​

Answers

Answer:

Step-by-step explanation:

We can use the identity for the cosine of the sum of two angles:

cos(a + b) = cos(a)cos(b) - sin(a)sin(b)

In this case, we can write:

cos(60°) = cos(55° + 5°) = cos(55°)cos(5°) - sin(55°)sin(5°)

We know that cos(60°) = 1/2, and we also know that cos(55°) = p. We can solve for cos(5°):

1/2 = p cos(5°) - sin(55°)sin(5°)

sin(55°)sin(5°) = p cos(5°) - 1/2

We also know that sin²(55°) + cos²(55°) = 1, so:

sin²(55°) = 1 - cos²(55°) = 1 - p²

Substituting this into the previous equation:

(1 - p²)sin(5°)² = p cos(5°) - 1/2

Rearranging and factoring:

p cos(5°) = 1/2 - (1 - p²)sin(5°)²

Using the fact that sin²(5°) + cos²(5°) = 1, we can substitute cos²(5°) = 1 - sin²(5°):

p cos(5°) = 1/2 - (1 - p²)(1 - cos²(5°))

Simplifying:

p cos(5°) = 1/2 - (1 - p²) + (1 - p²)cos²(5°)

p cos(5°) = 1 - 2p² + (2p² - 1)cos²(5°)

Solving for cos²(5°):

cos²(5°) = (1 - p cos(5°) + 2p²) / (2p² - 1)

Substituting the value we found for p, cos²(55°) = p²:

cos²(5°) = (1 - p cos(5°) + 2cos²(55°)) / (2cos²(55°) - 1)

Finally, substituting p = cos(55°):

cos²(5°) = (1 - cos²(55°) cos(5°) + 2cos²(55°)) / (2cos²(55°) - 1)

cos²(5°) = (2cos²(55°) - cos²(55°) cos(5°) + 1) / (2cos²(55°) - 1)

cos²(5°) = (cos²(55°) + 1) / (2cos²(55°) - 1)

Therefore, the value of cos 5° in terms of p = cos 55° is:

cos 5° = ±sqrt[(cos²(55°) + 1) / (2cos²(55°) - 1)]

Note that the sign of the square root is determined by the quadrant in which 5° lies. Since 5° is in the first quadrant, cos 5° is positive.
